Abstract: A pellet mill comprises a perforated annular pellet die having an axis of rotation and first and second ends; and a die carrier rotatable about an axis of rotation and having an annular recess for receiving the first end of the annular pellet die. Fixing devices are secured to the first end of the die and cooperating fixing devices are provided in the annular recess in the die carrier. The fixing devices and the cooperating fixing devices have a first position relative to one another permitting insertion of the first end into the annular recess by relative axial movement of the die and die carrier and a second relative position permitting the transmission of force between the fixing devices and the cooperating fixing devices to draw the die towards the die carrier into a clamped position. Various different devices are provided for generating the force. In addition centering devices are provided which are effective on drawing of the die towards the die carrier to center the die relative to the die carrier.

Abstract: Attached to the eccentric studs (25) for supporting and positioning press rollers (20) relative to an inner surface of the die (21) of a pellet mill are levers (30). Linked to the levers (30) is an adjusting means (31) that is provided with a position controller (47) whose position measuring means is constructed as part of the adjusting means (31) for the position of the press rollers (20). In this fashion, the gaps between press rollers (20) and die (21) can be regulated very exactly from the outside.
